CO2Art’s NEW IO Acrylic In-Tank CO2 Diffuser is a compact, transparent CO2 diffuser designed for efficient in-tank CO2 injection in planted aquariums. Its acrylic body blends cleanly into the aquascape, while the sturdy design helps protect against cracks and damage compared to more delicate diffuser styles.

The IO Acrylic Series uses CO2Art’s Nano CO2 Mist Technology ceramic membrane to break CO2 into streams of tiny bubbles. As CO2 passes through the porous ceramic surface, the increased bubble surface area helps improve dissolution into the aquarium water, giving aquatic plants more consistent access to carbon dioxide with less waste.

Stable CO2 injection helps planted aquariums get better results from lighting and fertilization, supporting stronger growth, healthier plants, and improved coloration. The replaceable ceramic membrane is easy to reinstall for maintenance, and the kit includes two high-quality suction cups for secure positioning on the aquarium glass. This diffuser is compatible with CO2-resistant tubing and is available in two sizes: small for aquariums above 4 gallons and below 40 gallons, and large for aquariums above 40 gallons.
